摘　　要：监测气溶胶中水溶性无机离子有助于深入理解颗粒物无机离子形成的大气化学过程,半挥发性无机组分的气固分配机制等。总结了文献中连续监测方法与传统膜采样方法的比对结果,综述了该方法在无机离子日变化及其来源分析、酸度、二次离子形成机制等方面的研究进展,并对存在的问题及应用前景进行了评述。The continuous instruments can be used to investigate not only the processes that govern the formation and removal of ions＇, but also gas/particle partitioning of semi-volatile components. Comparison between filter-based and continuous techniques was summarized. Ions diurnal variations, analysis of the sources, acidity on aerosol by the continuous measuring systems were reviewed. Moreover, existing problems and application prospects were also evaluated.
